Prefabricated 240-ton KHM26 House Wrapped in a Steel Shell Was Transported by Boat to its Final Site

The core of the KHM26 house was built from concrete and wrapped in a a steel shell welded into a single piece. The architects predicted the use of highly precise building techniques that would allow for the construction of a water-tight shell. Its lowest storey is set below ground level in order to function as a foundation and houses three rooms that can be used as bedrooms.
